About Me
Self Introduction
Autonym: YuXuan Wu; Pseudonym: Horikita Saku
Majored in artificial intelligence as an undergraduate.
Interested in the intersection of data science and natural sciences, particularly in the realms of biological information and astrophysical.
Currently conducting research on discrete representation and AI applications in bioinformatics and medicine, including GWAS and single-cell analysis.
Kaggle Master.
My personality
I appreciate quiet spaces, reading, listening to the rain and relishing a good cup of coffee.
My favorite book is If On a Winter’s Night a Traveler.
Probably a bit workaholic.

NeurIPS - Ariel Data Challenge 2025 - Gold Medal 7th
Predict the area ratio of planets and stars and the confidence level (uncertainty) sigma.
- Achieved the 7th(1%) in the NeurIPS Competition. Achieve my first gold medal.
- We have developed a method that spans from heuristic forward modeling to Gaussian processes, to deep learning, and to gradient boosting trees.
- Become Kaggle Competition Masters.
IceCube - Neutrinos in Deep Ice - Silver Medal(top3%)
Reconstruct the direction of neutrinos from the Universe to the South Pole
- Achieved the 21th in the Neutrinos and Astrophysics competition, ranking in the top 3% globally among all participating teams.
- Utilized a 3D point cloud convolution model based on the EdgeConv operator, developed various RNN models, and employed a multi-stage training method grounded in IceCube’s physical principles.
- This achievement also marks my first medal in Kaggle competitions.
HMS - Harmful Brain Activity Classification - Silver Medal(top2%)
Developed a model trained on Electroencephalography (EEG) signals and Spectrogram recorded from critically ill hospital patients to classify a variety of harmful brain activities.
- Achieved 38th place in the Neuroscience and Physiology competition, ranking in the top 2% globally among all participating teams.
- Developed a 1D model based on EEG signals and employed innovative training methods to create an effective 1D+2D multi-modal model.
